GCC modified for the FreeChainXenon project
bc17882341
This patch fixes an odd incomplete optimization within pragma expressions. For example, in this code: X := True; pragma Assert (X = True); pragma Assert (X); the first assertion was eliminated by the frontend (regardless of the optimization switches), while the second assertion was only eliminated by the backend and only with switch -O1 or similar. The problem was that the current value propagation was disabled for references immediately within pragma argument associations. This was meant to avoid a crash when such a reference appears in pragma Inspection_Point, but this wasn't a proper fix. The proper solution is rather to not expand references in pragma Inspection_Point at all. Actually, this expansion was enabled to avoid a yet another crash, when the parameter of pragma Inspection_Point is a prival (i.e. a renaming of private protected component). It turns out that none of these suspicious problematic fixes is no longer necessary. Cleanup related to fixes of current value propagation in expansion of attribute Loop_Entry. gcc/ada/ * exp_ch2.adb (Expand_Current_Value): Remove special case for references immediately within pragma argument associations. * exp_prag.adb (Expand_Pragma_Inspection_Point): Remove special case for privals. |

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
